[Gptfdisk-general] gdisk skip sectors when suggesting the 1st sector of a partition

[<u3...@ne...>]

All the existing partitions have their first sector immediately following 
the last sector of their prior partition.
Why gdisk suggest to start the 8th partition at sector #59424768? The last sector
of the 7th partition is at sector #59422999.
gdisk is 1.0.5.
